Added HXCPP configuration options for performance optimization.
I'm not sure which ones are enabled by default, so I simply added them all together.
Here's a brief description of the potential optimizations each new addition may bring:
HXCPP_GC_GENERATIONAL: Makes garbage collection scan mostly only recent, new memory in most cases.HXCPP_GC_DYNAMIC_SIZE: Automatically adjusts the GC memory strategy based on runtime conditions.HXCPP_CPP17: Uses the C++17 compiler, which may bring more modern and intelligent optimizations. (Some of these settings also depend on it)HXCPP_GC_BIG_BLOCKS: Increases memory capacity to near-unlimited, reduces memory fragmentation, and improves large resource loading capability. This also means the number of arrows is no longer limited (Before enabling this, I experienced crashes when the note count reached around 70k during casual play).HXCPP_FAST_LINK: Improves compilation speed (though I didn't really notice a difference).You can also download the build from https://github.com/HEIHUAa/CodenameEngine-HEIHUA/actions/runs/21208146062 for testing.
I tested this under modcharts, which have a significant impact on memory usage. With the frame rate capped at a maximum of 200, the test results showed that the 1% low FPS increased from around 75 to 150.
